Freehub body change compatibility

[Sollie]

I have a single speed kona unit with a formula dc52 hub (only single speed drive) and was wondering if anyone knew what freehub bodies were compatible so I can switch is to more then just a single. I would prefer not to have to buy a whole new wheel or rebuilding with a new hub.
Thanks
